Abstract

An active region of cathode interlayer in a tubular solid oxide fuel cell (SOFC) is structurally analyzed using a dual-beam focused ion beam/scanning electron microscope (FIB/SEM). The GDC (10 mol% gadolinia-doped ceria) cathode interlayer (about 1 μm in thickness) is dip-coated, and then sintered on YSZ (8 mol% yttria-stabilized zirconia) electrolyte. At 1150°C sintering temperature, the pores oriented more along the axial direction than the radial direction. The anisotropy of pore shape is accounted for the withdrawal force during the dip-coating of the GDC interlayer.
